Gamemode resets to Creative in new dimensions

[Qwalk]

Hi!

I've set up a Hexxit server but there is an issue with gamemodes.

Every time I join the server, my gamemode is set to creative (the default one in the server.propeties is gamemode=0 (survival)). So I have to manually change gamemode in the chat (I'm OP) to gamemode 0. Also every time I enter a new dimension the gamemode resets to Creative, Nether, The End, Dimensional Doors etc, and I have to manually change it back to creative. This only happens to me, not to my friend who is also Op.

What can I do?

I've tried changing force-gamemode to true, but it doesn't solve the problem.
